Over-the-counter (OTC) antibiotics are medications that can be purchased without a prescription to treat minor bacterial infections. While they offer convenience, improper use can lead to antibiotic resistance, allergic reactions, or ineffective treatment. True antibiotics are rarely available OTC in most countries, though topical forms for skin infections or antiseptic ointments may be sold. It’s crucial to know when an infection actually requires antibiotics and to follow proper dosage instructions. Always consult a healthcare professional before using any antibiotic to ensure safety, effectiveness, and to prevent contributing to the growing problem of antibiotic resistance.
